I just sent out my campaigns, which means that everything is working
perfectly! I am very very happy right now. And I just wanted to let you know that the
DataValidation service was really fantastic!

I have no requests. Your support was amazing, the process was seamless and you
guys saved us. We tried a different company and they never returned the lists. Thank you for
everything and we will continue to use your service.
— Daniel R. Donovan, maxeffectmarketing.com
I just tried really using MailChimp for the first time. Seems awesome. I
imported my list and was blocked from sending it out. Their help said to delete my last
import and try again. Well, then I’d have no one to send my email to! Did a little research
and found that I needed to clean my list. I’d never heard of such a thing. Found one guy
that would do it for $142. For my 419 names. Yikes! Searched some more and found you. Whew!
Fast, easy, awesome. Did what you said and my email was sent out, no problem. Thank you!
Awesome! I’ll keep using it!
— Trevor J., Jones Home Collective | Keller Williams Exclusive
Hi, thanks, it's the first time I've used your service and it really helped
me. I spent hours trying to remove email addresses in the hope that Mailchimp would accept
my 'new' list and nothing worked. I then used DataValidation and Mailchimp immediately
accepted my cleaned list. I wish I'd used you straight away.
— James R., jamesreddy.co.uk
The service has been terrific - I wasn’t expecting it to be so easy and
straightforward. It is great value for money.
— Helen H., MayDay Travel Marketing
Live chat was incredibly helpful as I had no idea what I was doing! This is
the first time we've had such a problem with bulk email (our last company email we sent out
was 2014, to give you some idea) and your team held my hand through the process. I will
be recommending Data Validation.
— Alix T., doetaylor.com
In less than two weeks we went from an 87% reputation to 98% with SendGrid. We
have pleased the ISP gods thanks to your team!
— Mikhail Avady, IP SmartUP
I was a bit desperate yesterday after MailChimp blocked one of my uploaded
lists. It is clear that DataValidation solved this very quickly. Thanks a lot!
— Yves Van Hee, Atradius
DataValidation saved my life! I had to migrate the newsletter campaigns from a
self-programmed system to Zoho Campaigns, and I recognized, too late, that the dataset was
horrible. Zoho blocked me during the first campaign.
— Hans-Henning Schulz, Deutscher Verlag für Gesundh
I LOVE your service. I’ve used the MailChimp integration, which works like a
dream. I will be recommending your service to all my MailChimp clients as a ”good practice”
tool to add to their arsenal.
— Bridget Gilchrist, Tin Soldier Ltd.
Thanks very much for cleaning my list, the service works very well.
— Ross Debos, Sunday SouLounge
Super. I didn't expect the Mailchimp integration. It made everything
— Philip Owen, volgatrader.com
The service I have received has been fantastic. Without any doubt the best
online service I have ever had. Thank you!
— Andrés Gómez-Peña, IDB
On our first eNews to nearly 2,500 subscribers, we had only 5 bounce-backs and
7 unsubscribes. No way that would have been possible without your service! Thanks,
DataValidation, for keeping us in compliance!
— Jodie Rogers, University of Oregon
You guys are awesome. I've been looking for a platform like this for 2 months
to vet media contacts for my startup so I don't trash our domain in spam traps. This was the
most effective tool I've found, and I'll be using it again on the consumer side as we
develop a direct email marketing campaign.
— Jared Criscuolo, seededbox.com
Y’all have a great service with a nice clean, user friendly interface. Glad to
be able to have multiple versions of our list to make use of. No doubt I’ll be using the
services of your company again in the near future.
— Cody Reid, Brunk Auctions
I'm very pleased with how fast I got a reply to my questions. Also very
satified with the price and service. Great job.
— Joshua Guilfoyle, New York City, NY
Very useful — helped us get over the hump with our first import of
6-year old data to MailChimp. Now running much more smoothly!
— Alex English, Tampa Bay Regional Transportation Authority (TBARTA)
Thanks Data Validation! It was easy to use and after I studied the
definitions, I was able to re-sort my data for upload to MailChimp. In addition, your tips
about sending emails to the Accepts All emails was extremely helpful!
— Jennifer Hoskins, PHR
It's awesome!! I was able to import the cleaned list of A's and B's into
MailChimp no problem, whereas before cleaning with DV, MailChimp let me know a re-opt in
would be required. I'm thrilled with this service!
— Lily Starling, ParkWinters.com
We tried DataValidation on advice from a colleague. The service was easy to
link to Mailchimp, and was extremely affordable.
— Jodie Rogers, University of Oregon
We are VERY satisfied. Your service has refreshed our stale mailing list and
contributed to the surrealistic celebration of the Domestic Research Society's 10th
anniversary - high in the Julian Alps!
— Alenka Pirman, Domestic Research Team
Your service has been outstanding, and I especially liked your LiveChat
feature - very helpful!
— Karen Burke, Crop King
We saved thousands of dollars that would have been spent on bounces and
opt-outs by using DataValidation's cleaning tools. Now, we use their real-time protection so
we never have a bad list again.
— Blake, Perdue for Senate
Thank you very much! Your service is super!
— Lexi Serebro, ToneDef.co.za
Thanks for your service, it was helpful and easy to use! MailChimp knew what
they were doing when they recommended you.
— Abby Rubottom, FloridaPromise.org
We are very pleased with your service and fast turnaround time. We ran a small
list through and then sampled those emails through our email platform.
